If a spoon of copper metal is placed in a solution of ferrous sulphate

Question

If a spoon of copper metal is placed in a solution of ferrous sulphate (A) Cu will precipitate out (B) iron will precipitate (C) Cu and Fe will precipitate (D) no reaction will take place

Tardigrade Admin · Accepted Answer

EoCu2+|Cu=0.34 EoFe2+|Fe=-0.44 V So Cu can’t displace Fe2+.

Q. If a spoon of copper metal is placed in a solution of ferrous sulphate

Cu will precipitate out

iron will precipitate

Cu and Fe will precipitate

no reaction will take place

$E_{C u^{2 +} ∣ C u}^{o} = 0.34 E_{F e^{2 +} ∣ F e}^{o} = - 0.44 V$
So Cu can’t displace $F e^{2 +}$ .

Q. If a spoon of copper metal is placed in a solution of ferrous sulphate

Cu will precipitate out

iron will precipitate

Cu and Fe will precipitate

no reaction will take place

ECu2+∣Cuo​=0.34EFe2+∣Feo​=−0.44V So Cu can’t displace Fe2+.

$E_{C u^{2 +} ∣ C u}^{o} = 0.34 E_{F e^{2 +} ∣ F e}^{o} = - 0.44 V$
So Cu can’t displace $F e^{2 +}$ .
